Guinness Sustainable Energy Fund on Owens Corning

Thesis

The fund owns Owens Corning for exposure to insulation and building efficiency. The managers see higher power prices as improving the payback from efficiency products and expect progressively tighter efficiency standards to support long-term demand. Insulation is a direct way to reduce building energy consumption, making Owens Corning a demand-side beneficiary of the energy transition.
